Armalcolite nanocomposite: A new paradigm for flexible capacitive humidity sensor

In this paper, a unique Armalcolite-PDMS-based flexible capacitive humidity sensor is designed by using spin coating technique, which uses interdigitated gold (Au) electrode and ultrathin (similar to 80 mu m) flexible polyimide substrate. The structural and morphological properties of the Armalcolit...
